IPC: H04N7/14
Filed: 1988-08-31
Abstract: PURPOSE:To surely prevent missing of useful pattern information stored already by using a selection signal of an operating button so as to set and release the write protection of pattern information to a storage area of a memory device. CONSTITUTION:The pattern information received by a communication equipment 3 is stored in a memory device 1 by a controller 6 and displayed on a display device 2. In this case, based on a depression signal of a operating button 5, the controller 6 controls the memory device 1 to select the setting/release of the write protection of the pattern information. Thus, even if the pattern information is received by the communication equipment 3, since no write is applied to the area of the memory device with write protection set thereto, the pattern information stored in the area is not lost.

Title: Infrared image pickup device
Inventor: YAMAKAWA HIDEO
IPC: G02B7/02
Filed: 1987-08-31
Abstract: PURPOSE:To obtain an infrared image pickup device which can compensate an out-of-focus generated due to a temperature change, by inserting and holding an image forming lens by two springs, and forming one of said springs by a high expansion coefficient material. CONSTITUTION:A temperature compensating part 6 is constituted of a spirally wound high expansion coefficient material 8, a spring 10 and an image forming lens 9, and the image forming lens 9 forms an infrared image on an image pickup detector 7. The high expansion coefficient material 8 forms a spiral spring and expands and contracts in accordance with a change of a temperature. When the high expansion coefficient material 8 starts to expand as a temperature rises, a position of the image forming lens 9 moves, while keeping the balance with the other spring 10. On the other hand, when a temperature falls, the high expansion coefficient material contrasts, and simultaneously, the spring 10 expands and pushes the image forming lens 9, and moves the image forming lens 9 in the direction reverse to the case of the rise. In such a way, even if a temperature of the environment changes, a distinct infrared image can always be formed.
